Question about In Microwave Ovens

Where to start in troubleshooting?

Hello, my microwave has died out of warranty, only used for 3 months, and was heating a small bowl of pasta when it quit. It is completely dead. Where should I start in troubleshooting it? I haven't worked on a mocrowave before, but I have fixed SMPS and other line voltage electronics. Any help would be appreciated.

    I'd like to add that the main fuse was blown when I removed the cover.

    I replaced the main fuse and it started working again, tried it with a bowl of soup. Is it likely the fuse blew due to poor airflow around the microwave?

My recently purchased Rival RGST902 microwave stopped heating. Everything else works, it just will not heat.


The first wayout is to consider WARRANTY.If the microwave is under warranty return it to the point of purchase to enjoy warranty right.But if the microwave is not under warranty another wayout is needed.

Below is the solution on how to make our microwave heat food.

1 Remove oven racks and place them in soapy water to soak.

2 Preheat oven to 200 degrees.

  • 3 Turn the oven off and spray the inside with oven cleaner.

  • 4 Allow to sit for 10 minutes.

  • 5 Wipe the cleaner and dirt away with a damp sponge, rinsing frequently.

  • 6 Dry with a soft cloth.

  • Thanks.

    Microwave taking much longer to heat food

    The microwaves are produced by what is known as a KLYSTRON TUBE. Like anything, early failure is possible. There is also the possibility that the transformer or electronic circuit providing the correct voltage to the KLYSTRON has failed, either from over-use, manufacturing defect, or leakage from the KLYSTRON enclosure, which creates heat.
    With microwaves being as CHEAP as they are, replacement should not be an issue.

    Sharp microwave losing cooking power

    If the supply voltage is low it will take long time to heat foods. The second reason is the Magnetron. Since it is in the warranty period you can call at the sharp authorised service center. They will do it free of coast.

    Microwave shuts off about 10 - 30 after starting to heat an item. Display flashes PF. Which I figure is power failure. Unit is 5 months old and has very little use. Model WES1130DM1WW purchased at...

    It should have a one year warranty, right? If so, Westinghouse should take care of it for you.

    No heat

    COINCIDENCE? Yes... :) So go buy another one, it'd probably be cheaper than getting the bad one repaired.
